Engraving FNFAL or Snake FNFAL

Hi guys, I plan on trying for a Engraving or Snake FNFAL after I win a Skull Gattling Gun when I buy AP next time. Which one is better? People in game say Engraving but then Snake is hot and Engraving is forgotten so which one?

After a while I will total the results and see which side will win the battle...SNAKE or ENGRAVING!!!
